(p. 156-158)The four types of system units are: tablet PC system unit,
desktop system unit, notebook system unit, and PDA system unit. The desktop
system unit can be placed horizontally (desktop) or vertically (tower). All
input devices are located outside the system unit. The notebook system unit is
portable and contains some integrated input devices, like a pointer and
keyboard. Tablet PC system units are similar to notebooks, but are designed to
use a stylus as the primary input device. The PDA system unit is very small
(palm sized) and contains the entire computer system.
67.
(p. 158)The three binary coding systems are ASCII, EBCDIC, and
Unicode. ASCII is the most widely used system. EBCDIC was developed by IBM for
use in large computers. Both of these systems use 8 bits per byte. Unicode was
developed with funding from several large software companies. It uses 16 bits
per byte to facilitate the storage of complex international alphabets.
68.
(p. 162)A microcomputer has a single CPU which does not allow the
computer to process heavy tasks. But with the help of a dual-core chip, even a
microcomputer can run all the complex programs that only large computers could
do. This is done through parallel processing.
69.
(p. 162)Parallel processing is the simultaneous use of more than one
CPU to run a program that allows faster execution and improved performance.
70.
(p. 162-163)A smart card is essentially a plastic card the size of a
regular credit card that has an embedded chip. It can store 80 times the
information stored on the magnetic strip of a regular credit card. It is used
for identification, providing access to a network, securing cellular phones,
securing set-top boxes on televisions, storing medical files, personal records
etc.
71.
(p. 163-164)Flash RAM or flash memory chips can retain data even if
power is disrupted. This type of RAM is the most expensive and used primarily
for special applications such as for digital cell telephones, digital video
cameras, and portable computers. It is different from other types of RAM
because it is considered as non-volatile RAM.
72.
(p. 166)While both allow you to connect to other computers, they work
in different ways. A modem translates an audio signal to connect you via the
telephone system. An NIC is used when this translation is not needed, such as a
network.
73.
(p. 170)Industry standard architecture (ISA), Peripheral component
interconnect (PCI), Accelerated graphics port (AGP), Universal serial bus
(USB), and FireWire buses (HPSB).
74.
(p. 170)A serial port can only send one data bit at a time and is very
good for sending data over a long distance. Parallel ports can send 8 bits at a
time and are primarily used to connect printers.
75.
(p. 171)An IrDA transmits infrared signals. Using this, we can
transfer data from one device to another without any cables. For example, if
both your desktop computer and printer have IrDA ports, you can simply put your
computer near the printer and take printouts without needing to connect the two
with a cable. The only thing is the two machines need is to be near each other.
